JEFFERSON D. YOUNG, 0F CHATTANOOG-A, OKLAHOMA, ASSIGNOR TO THE BOLTLESS RAIL JOINT COMPANY, OF WILMINGTON, DELAWARE, A CORPORATION.

Application filed February 5, 1913.

Specification of Letters Patent.

Serial No. 746,331.

To all whom it may concern Be it known that I, JEFFERSON D. YOUNG, a citizen of the United States, residing at Chattanooga, in the county of Comanche and State of Oklahoma, have invented certain new and useful Improvements in Safety Boltless Rail-Joints; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to a boltless safety and self-compensating rail joint, and my prime object, among others, is to provide a joint which will insure absolute safety without the use of locking bolts usually employed to hold the meeting ends of the rails together.

A further object of my invention, among others, is to so look the meeting ends of the rails that the width of the supporting base for the rail proper is greatly multiplied, thereby providing reliable means for holding the rail against lateral strain or movement. 5

Other objects and advantages will be here inafter made clearly apparent, reference being had to the following specifications considered in connection with the accompanying drawings, in which, 1

Figure 1 shows a transverse section of my rail oint and indicating the position of the rail relative to the supporting and locking elements. Fig. 2 is a side elevation of Fig. 1 on a reduced scale showing a part of the rail chair or base broken away.

In describing my invention, it may be stated that in my former work, and in the work of others providing a supporting base for the rail, the base proper of the rail is designed to rest in direct contact with the supporting base or chair, whereas, I wish to call particular attention to the fact that I have suspended the base of the rail slightly above the supporting base or chair by means of the supporting and locking members disposed upon either side of the track rail, as will be specifically pointed out.

Referring in detail to the drawings, l in dicates the supporting base, provided with vertical flanges 2 near its outer edges tapered at its extreme edge and provided with suitable recesses 3 to receive the spike 4:- Between the flanges 2, I provide a space of proper width to snugly receive the base 5 of the track rail, and I also provide the bracing members 6 and 7, the upper edges 8 of which are so formed as to fit snugly under and in direct contact with the tread 9 of the rail and the contiguous part of the Web 10, as will be clearly apparent by reference to Fig; l. The lower edges of the bracing members (Sand 7 are provided with the in clined faces 11, designed to fit corresponding seats in the inner walls of the flanges 2 and formed with the upwardly inclined faces 12 fitting a similar seat formed in the flanges 2 directly below the seat or face occupied by the wall 11. The extreme lower edges of the bracing sections 6 and 7 are formed with beveled terminals 13, shaped to fit directly upon the contiguous part of the base 5 of the track rail. The bracing-sections 6 and 7 are of such height when disposed in their 0perative positions that the track rail Wlll be held above and out of contact with the base 1, as indicated by the clearance 1&, whereby the track rails are suspended above the base, inasmuch as all of the weight of the, passing train is placed directly upon the bracing sections 6 and 7 and distributed to the base member or chair, through the terminal faces 11 and 12, and by reason of the special form of seating provided in the base or chair, the base of the rail is held against any move ment whatever. It is obvious, therefore, that by reason of the outwardly and downwardly inclined supporting braces 6 and 7, ample space or clearance is provided, as indicated by the numeral 15, between said braces and the web of the rail, whereby bonding members 16 may be conveniently and safely located, inasmuch as said bonding members will be disposed safely within a housing which will render them inaccessible except when one or both of the bracing sections 6 and 7 are removed. Each of the meeting ends of the rails thus joined together is provided with a suitable notch in the edge of the base which is designed to fit around the lug 17 the said notch being so formed that full com pensation is made for expa melon and contraction and the incident longitudinal movement of the track rail. It will be observed by reference to Fig. 2 of the drawings that the lug 17 is seated in a suitable aperture provided in the base 1, the lower end of said aperture being enlarged, whereby the anchoring Patented July 7, 1914.

-Moreover, the bracing sections being dis stem 18 of the lug 17 may be upset or enlarged to prevent the casual removal thereof from its adjusted position.

I have provided, preferably near the dle of each of the flanges 2, an aperture so located that when the locking pin 19 is disposed therein, part of said pin will enter.

a recess or groove in theouter edge of the bracing sections 6 and '7, and thus prevent longitudinal movement of said bracing sections, it being understood that a suitable locking key 20 may be entered in the aper-,.

ture 21 to hold said pin against casual displacement. The track rail being thushead-supported by the outwardly inclined bracing sections 6 and 7-, disposed as they are immediately under the tread portion of the rail and re liably seated in their lower edges, it follows that such bracing sections tend in their action' to most tightly grip the interposed rails when'theload is applied thereon, thus trans mitting the load on the tread of the rail in a diverging direction to the chair member, thereby reducing the wear to a mlnlmum.

posed directly under the head or tread portion of the rail prevent the rail from having any rolling or lateralmovement Whatever. The track rail thus equipped will be held against all lateral movement, thereby mak ing it possible to dispense with the ordinary bracing blocks commonly employed for that purpose.

By reason of the eculiar formation of the upper and lower e ges of the bracing sections 6 and 7 any possible wear that may result would be fully compensatedfor by reason of the clearance-1 1 and at the same time the locking grasp of the coperating parts upon each other will'be fully maiiitained throughout the life of the rail.

\Vhat I claim is: i 1. A herein described rail join't'comprismg a chair member, vertical and parallel flanges formed on the sides of sai d' 'chair, a

- I rail to be received between said flanges and spaced from the bottom of achair, sald flanges extending above said base of the rail, a pair of straight bracing sections having one edge fitted directly under the head of the rail and in contact with the contiguous portion of the web thereof, said sections diverging downwardly and having the lower edge thereof enlarged and substantially hexagonal in transverse cross sections and pro- Gopies of this patent may be obtained for five cents each, by addressing vided with five faces having substantially the relation to each other of the five faces prising a chair member, vertical and parallel I flanges formed on the sides o-fsaid chair, the rail to be received between said flanges'and spaced fromthe bottom of said chair, said flanges extending above the base of'said rail, a pair ofstraight bracing sections having one edge fitted directly under the head of the rail in contact with a contiguous portion of the webthereof, said sections diverging downwardly and having their lower edges enlarged and substantially hexagonal in transverse cross sections, and formed with five hexagonal faces, said flanges of the chairs having inwardly over hanging edges each forming a recess and a vertically extending aperture therein extending through the base of the chair and communicating with said recess, said flanges having faces to receive three of said faces of said brace while the other of the faces thereof rests upon the base of the rail, the outer edge .of

said; enlarged edge of the brace being notched and adapted to register with the apertures through the flange and chair, one ofsa1dfaces of the flanges and braces being at right angles to the hue of compresslon rail will be directly transmitted to said face, and apin adapted to extend through and be secured in s'aid apertures for holding said brace members rigidly in the position set v strain so that the weight applied upon the forth, thuspreventing any longitudinal, lateral or vertical movement of the brace members.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
